Abstract
A green protocol involving novel three-component one-pot cyclocondensation reactions of 2- amino-4-aryl-thiazoles, aromatic aldehydes and ammonium thiocyanate under solvent-free microwave irradiation (MWI) conditions expeditiously yields thiazolo-s-triazine nucleobases, which afford the corresponding pyrano N-nucleosides on I2 promoted glycosylation with 1,2,3,4-tetra-O-acetyl- β-D-ribo- /xylopyranose under MWI followed by deacetylation.
Keywords: Multicomponent reactions, solvent-free, glycosylation, microwaves, thiazolo-s-triazines, pyrano N-nucleosides
